Physicists of the University of Bonn have taken one more important hurdle on the path to what is known as a quantum computer: by using 'laser tweezers' they have succeeded in sorting up to seven atoms and lining them up.
According to a study that appears in the November 2006 issue of the journal Ophthalmology, researchers at the University of Pennsylvania School of Medicine and 21 other clinical centers have found that low-intensity laser treatment - thought to be potentially beneficial in slowing or preventing the loss of vision from age-related macular degeneration (AMD) - is ineffective in preventing complications of AMD or vision loss.
Physicists at the National Institute of Standards and Technology (NIST) have used lasers to cool and trap erbium atoms, a "rare earth" heavy metal with unusual optical, electronic and magnetic properties.
Following up on their well-received first book, Laser Beam Shaping: Theory and Techniques, Sandia National Laboratories researchers Fred Dickey and Scott Holswade have edited (with David Shealy of the University of Alabama at Birmingham) a compact new volume, Laser Beam Shaping Applications.
Engineers and applied scientists from Harvard University have demonstrated a new photonic device with a wide range of potential commercial applications, including dramatically higher capacity for optical data storage.
Fourteen laser ranging stations participated in a campaign to track ESA's GIOVE-A satellite during the spring and summer of 2006, providing invaluable data for the characterisation of the satellite's on-board clock.
Physicists and medical researchers for the first time have demonstrated a new technique that non-invasively measures in real time the level of damage to the skin from sun exposure and aging, and initial results suggest that women's skin ages faster than men's.
The Georgia Institute of Technology's Center for Organic Photonics and Electronics (COPE) and Solvay announced a $3 million deal for OLED research today.
The most powerful tunable laser in the world just shattered another power record: the Free-Electron Laser (FEL), supported by the Office of Naval Research and located at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab), produced a 14.2 kilowatt (kW) beam of laser light at an infrared wavelength of 1.61 microns on October 30.
An artificial, laser-fed star now shines regularly over the sky of Paranal, home of ESO's Very Large Telescope, one of the world's most advanced large ground-based telescopes.
Cotton may be getting even more breathable. A new wave of fiber research debuts with an international science and technology conference.
The multi-satellite Darwin mission will use optical interferometry in which at least three separate orbiting telescopes jointly operate as an equivalent single telescope with a much larger effective aperture, thus achieving the required resolution.
We have to climb a mountain in order to conquer it. In quantum physics there is a different way - objects can reach the opposite side of a hill simply by tunnelling through it, instead of laboriously climbing over it.
The International Society for Optical Engineering will honor 56 new Fellows of the Society this year.
A new type of diode laser, called the quantum cascade laser (QCL), may eventually change this situation. Diode lasers are inherently compact and suitable for mass-production, which has led to their widespread and low-cost use in everyday products, including CD and DVD players.
